includes the integral traction sheave 42. Rotation of the motor 58 causes the
traction sheave 42 to rotate and drive the ropes 24.
Mounting the machine 26 on the beam 52 permits the machine 26 to be
positioned within the hoistway, thereby eliminating the need for a machineroom.
In addition, the beam 52 transfers the load of the machine 26 and the load from
the engagement between the traction sheave 42 and the ropes 24 directly to the
pit 62 of the hoistway. As a result, the machine 26 may be positioned at the top
of the hoistway and the loads may be carried by the foundation of the building
that houses the elevator system 10.
The other beam 64 is used to conveniently mount the governor 28 and its
associated tension frame 66, and provides a termination point to fix the dead-end
hitch 38 for the ropes 24. By fixing the dead-end hitch 38 to the beam 64, the
loads from the ropes 24 are transferred through the dead-end hitch 38 to the
beam 64, and thereby to the pit 62 of the hoistway and foundation of the building.
This permits more of the elevator 10 loads to be transferred directly to the
foundation using the beams 32 as conduits for the loads.
Each of the beams 32 is a structural stress, I-shaped structure, as shown
more clearly in FIG. 2, and includes a pair of flanges 68,72 and a cross-member
74. A benefit of using such an I-beam as the mounting beam is that such
structures are readily available, are relatively inexpensive, and have well known
strength characteristics. Other structural members having different configurations
and formed from different materials, however, may also be used to support the
traction machine 26 and elevator 10 loads. In addition, each beam 32 may be a
single, integral member as shown, or may be formed from a plurality of segments
joined end-to-end to extend through the hoistway.
Rodosta's invention relates to automobile lift devices, and more particularly to a
hydraulically-operated automobile lift assembly of the type provided with a platform
slidably-engaged with upstanding posts at the corners of the assembly. A main object
of the invention is to provide a novel and improved power-operated automobile lift
